Co-authored-by: @ahesford The direction of resizing was determined based on the hovered ssd component (e.g. left border, top-left extent), but it caused problems when trying to start resizing by pressing the corners of the window border; the resizing direction was always unidirectional at bottom corners and resizing cannot be started by pressing top corners. This commit fixes this weirdness by determining resize directions only based on the window geometry and the cursor position. The corner extents are removed as they are not longer needed. This commit also adds <resize><cornerRange> which configures the range of corner resizing on the borders/extent.
